ntp_conf resource

[edit on GitHub]

Use the ntp_conf Chef InSpec audit resource to test the synchronization settings defined in the ntp.conf file. This file is typically located at /etc/ntp.conf.

Availability

Installation

This resource is distributed along with Chef InSpec itself. You can use it automatically.

Version

This resource first became available in v1.0.0 of InSpec.

Syntax

An ntp_conf resource block declares the synchronization settings that should be tested:

describe ntp_conf('path') do
  its('setting_name') { should eq 'value' }
end

where

• 'setting_name' is a synchronization setting defined in the ntp.conf file
• ('path') is the non-default path to the ntp.conf file
• { should eq 'value' } is the value that is expected

Examples

The following examples show how to use this Chef InSpec audit resource.

Test for clock drift against named servers

describe ntp_conf do
  its('driftfile') { should eq '/var/lib/ntp/ntp.drift' }
  its('server') do
    should eq [
      '0.ubuntu.pool.ntp.org',
      '1.ubuntu.pool.ntp.org',
      '2.ubuntu.pool.ntp.org'
    ]
